Audio Visualizer Script Error
is it because your filepath is not a valid filepath?

Either use a prefix r to make the path raw, or use forward slashes. Backslashes have special meaning in programming languages like python. valid paths are

   # windows
   filepath = "C:\\some\\folder\\file.mp3"
   filepath = r"C:\some\folder\file.mp3"
   filepath = "C:/some/folder/file.mp3"

   # posix style (linux, osx)
   filepath = "/home/folder/file.mp3"


This bug is fixed as of today: this error will now return 'File not found', which is better:
